  59           The Extended Industry Standard Architecture (EISA) bus was
  60           developed as an open alternative to the IBM MicroChannel bus.
  61
  62           The EISA bus provided some of the features of the IBM MicroChannel
  63           bus while maintaining backward compatibility with cards made for
  64           the older ISA bus.  The EISA bus saw limited use between 1988 and
  65           1995 when it was made obsolete by the PCI bus.

1295           Say Y to include the NWFPE floating point emulator in the kernel.
1296           This is necessary to run most binaries. Linux does not currently
1297           support floating point hardware so you need to say Y here even if
1298           your machine has an FPA or floating point co-processor podule.
1299
1300           You may say N here if you are going to load the Acorn FPEmulator

1308           emulator.  Otherwise, only 32 and 64-bit support is compiled in.
1309           Note that gcc does not generate 80-bit operations by default,
1310           so in most cases this option only enlarges the size of the
1311           floating point emulator without any good reason.

1319           Say Y here to include the FAST floating point emulator in the kernel.
1320           This is an experimental much faster emulator which now also has full
1321           precision for the mantissa.  It does not support any exceptions.
1322           It is very simple, and approximately 3-6 times faster than NWFPE.
1323
1324           It should be sufficient for most programs.  It may be not suitable
1325           for scientific calculations, but you have to check this for yourself.
1326           If you do not feel you need a faster FP emulation you should better
1327           choose NWFPE.
